Problems solved by technology

However, the disaster-affected area quickly delineated by seismic intensity and digital isoseismal line estimation is generally much larger than the actual disaster-affected area, and it takes a long time to determine the disaster-affected area after collecting high-definition images of the disaster-affected area through remote sensing means such as drones. Therefore, there is an urgent need to develop A method that can quickly and accurately determine the scope of the disaster area

Abstract

The invention discloses a moving target emergency tracking system and method and a seismic hazard range determining system and method. The moving target emergency tracking system comprises a server and a mobile terminal, and a moving target database is established at the server; when an emergency tracking event occurs, the server screens out a tracking target and sends an emergency tracking request to the mobile terminal carried by the tracking target; the mobile terminal receives and analyzes the request and sends current position information to the server so that emergency tracking can be started. The seismic hazard range determining method comprises the following steps that firstly, a rough disaster area range is determined according to the epicenter and intensity, a moving target permanently staying in the rough disaster area range is screened out, emergency tracking is conducted on the moving target, the feedback position of the moving target is obtained, the rough disaster area range is divided into a plurality of sector units with the epicenter as the center, and points, closest to the epicenter, of all the units are connected in sequence so that a more accurate severely-damaged area of a disaster area can be obtained. The moving target emergency tracking system and method and the seismic hazard range determining system and method can reduce the network transmission data volume, reduce the storage pressure on the database of the server and improve the determining efficiency of the severely-damaged seismic hazard area.

Description

technical field [0001] The invention belongs to the technical field of service based on spatial position, and in particular relates to a system and method for emergency tracking of moving targets and determination of earthquake disaster range. Background technique [0002] In recent years, smart terminals with built-in GPS / GNSS (such as GPS, GLONASS and Beidou navigation system) have been widely used around the world. According to reports, in 2013, the shipment of smartphones exceeded 1 billion for the first time, and the number of users was nearly 2 billion. Since the smart terminal has functions such as real-time positioning, communication, and photography, it provides the possibility for emergency / on-demand tracking services for ground moving targets. At present, the real-time tracking system has been well applied in many industries. For example, the vehicle-mounted GPS real-time tracking system has been widely used in intelligent transportation, navigation, police, emer...
